Several years ago, Kids Fly Safe invented the Child Aviation Restraint System (CARES), a harness-style seat belt designed to provide in-flight upper- body support (in lieu of a car seat) for children weighing 22 to 45 pounds, and up to 40 inches tall. Now the company has gotten FAA approval (with some restrictions) for the Special CARES Flight Belt, a similar harness designed for bigger special-needs children, as well as special-needs adults up to 6 feet tall. The harness, which attaches to the seat via a strap that slides over the seat back, functions like those used by flight attendants and pilots, keeping the chest and shoulders from jerking forward during sudden stops. The FAA requires that those using the Special CARES flight belt be seated in the back row of their compartment, and get a special permit in advance from the FAA (Kids Fly Safe has details on its website). There are no such requirements for children meeting the size and weight limits of the standard CARES belt. Both models weigh about a pound and stuff into the small included pouch.
